1.) a.) If 1 km = 1,000 m and 1 m = 1,000 mm, Convert 2.0 x 10⁶ mm into the equivalent value in km.

b.) There are 1,760 yards in a mile and 0.621 miles in 1 km. If you sprinted the equivalent of 20 football fields (each 100 yrds long), how many miles did you sprint?

c.) If there are 1.609 km in a mile, convert 135 miles/hour into meters per second. (There are 1000 m in a kilometer.)

The rigid beam is supported by the three suspender bars. bars ab and ef are made of aluminum and bar cd is made of steel. if each bar has a cross-sectional area of 450 mm2, determine the maximum value of p if the allowable stress is (σallow)st = 200 mpa for the steel and ( σallow)al = 150 mpa for the aluminum. est = 200 gpa and eal = 70 gpa.
